You should see the Android system recovery options' list at the top of the screen. Use the Volume buttons to highlight/select the options and the Power button to confirm the one you want.

Some useful options to select are:

- Reboot system now: this option will restart the device normally.

- Wipe data/factory reset: this option will wipe all of your data — photos, videos, music, apps, everything — and return your phone to its original factory condition. This will also wipe the cache partition. It's recommended expecially after a ROM update or to fix some bad problems.

- Wipe cache partition: this option will delete temporary system data, only related to app installations: you will not lose any personal data or settings. Wiping the cache partition can sometimes fix issues and device slowdowns.
